Currently the wrong flag is used to activate the cluster position corrections. The matcher uses the useTrackPositionClusterCorrection flag instead of useClusterCorrectionPosition. Matcher: https://github.com/JeffersonLab/hps-java/blob/master/recon/src/main/java/org/hps/recon/utils/TrackClusterMatcherMinDistance.java#L129 Called by: https://github.com/JeffersonLab/hps-java/blob/master/recon/src/main/java/org/hps/recon/particle/ReconParticleDriver.java#L524 Is this intended ? @alspellm @sarahgaiser @mholtrop
